You can, in fact it is helpful. Just two provisios with getting on with you life. 1 - getting on with your life doesn't involve dating someone else. 2 - getting on with your life doesn't mean pursuing a divorce.
Dating other people right now; your a mess, only going to hurt everyone involved anyway. Divorce? Hell you are pretty much divorced right now at least the life style, so you don't need the paperwork to prove anything. Give up, but keep the hope or better yet the faith somewhere you can get ahold of it later.
